ETL. The bot relies on information and knowledge extracted from the raw data by an ETL process in the backend. This data might be structured (SQL database), semi-structured (CRM system, FAQs), or unstructured (Word documents, PDFs, web logs). An ETL subsystem extracts the data on a fixed schedule. The content is transformed and enriched, then loaded into an intermediary data store, such as Cosmos DB or Azure Blob Storage.
“They’re doing things we’re simply not doing in the U.S. Imagine if you were going to start a city from scratch. Rather than having to deal with all the infrastructure created 200 years ago, you could hit the ground running on the latest technology. That’s what China’s doing — they’re accessing markets for the first time through mobile apps and payments.” — Brian Buchwald, CEO of consumer intelligence firm Bomoda
The NLP system has a wide and varied lexicon to better understand the complexities of natural language. Using an algorithmic process, it determines what has been asked and uses decision trees or slot-based algorithms that go through a predefined conversation path. After it understands the question, the computer then finds the best answer and provides it in the natural language of the user.
Businesses are no exception to this rule. As more and more users now expect and prefer chat as a primary mode of communication, we’ll begin to see more and more businesses leveraging conversational AI to achieve business goals—just as Gartner predicts. It’s not just for the customer; your business can reduce operational costs and scale operations as well.
In this article, we shed a spotlight on 7 real-world chatbots/virtual assistants across industries that are in action and reaping value for their parent companies. From streamlined operations and saved human productivity to increased customer engagement, the following examples are worth a read if you’ve ever considered leveraging chatbot technology for your business (or are curious about the possibilities).
The idea was to permit Tay to “learn” about the nuances of human conversation by monitoring and interacting with real people online. Unfortunately, it didn’t take long for Tay to figure out that Twitter is a towering garbage-fire of awfulness, which resulted in the Twitter bot claiming that “Hitler did nothing wrong,” using a wide range of colorful expletives, and encouraging casual drug use. While some of Tay’s tweets were “original,” in that Tay composed them itself, many were actually the result of the bot’s “repeat back to me” function, meaning users could literally make the poor bot say whatever disgusting remarks they wanted.
Since 2016 when Facebook allows businesses to deliver automated customer support, e-commerce guidance, content and interactive experiences through chatbots, a large variety of chatbots for Facebook Messenger platform were developed. In 2016, Russia-based Tochka Bank launched the world's first Facebook bot for a range of financial services, in particularly including a possibility of making payments.  In July 2016, Barclays Africa also launched a Facebook chatbot, making it the first bank to do so in Africa.

Clare.AI is a frontend assistant that provides modern online banking services. This virtual assistant combines machine learning algorithms with natural language processing. The Clare.AI algorithm is trained to respond to customer service FAQs, arrange appointments, conduct internal inquiries for IT and HR, and help customers control their finances via their favorite messaging apps (WhatsApp, Facebook, WeChat, etc.). It can even draw a chart showing customers how they’ve spent their money.
Other bots like X.ai can help schedule your meetings for you. Simply add the bot to your email thread, and it will take over back-and-forth conversation needed to schedule a meeting, alert you once it’s been arranged and add it to your calendar. As bot technology improves, the thinking is that bots will be able to automate all kinds of things; perhaps even something as complex as your taxes.
Cheyer explains Viv like this. Imagine you need to pick up a bottle of wine that goes well with lasagna on the way to your brother's house. If you wanted to do that yourself, you'd need to determine which wine goes well with lasagna (search #1) then find a wine store that carries it (search #2) that is on the way to your brother's house (search #3). Once you have that figured out, you have to calculate what time you need to leave to stop at the wine store on the way (search #4) and still make it to his house on time.
The educators or class organizers can opt for chatbots to simplify daily routine tasks. Chatbots may serve as a helping hand to the teacher in dealing with the daily queries by allowing bots to answer the questions of students on a daily basis, or perhaps even check their homework. Eventually, they offer teachers more time to work with their students on a one-by-one basis.
Context: When a NLU algorithm analyzes a sentence, it does not have the history of the user conversation. It means that if it receives the answer to a question it has just asked, it will not remember the question. For differentiating the phases during the chat conversation, it’s state should be stored. It can either be flags like “Ordering Pizza” or parameters like “Restaurant: ‘Dominos’”. With context, you can easily relate intents with no need to know what was the previous question.
ELIZA's key method of operation (copied by chatbot designers ever since) involves the recognition of cue words or phrases in the input, and the output of corresponding pre-prepared or pre-programmed responses that can move the conversation forward in an apparently meaningful way (e.g. by responding to any input that contains the word 'MOTHER' with 'TELL ME MORE ABOUT YOUR FAMILY'). Thus an illusion of understanding is generated, even though the processing involved has been merely superficial. ELIZA showed that such an illusion is surprisingly easy to generate, because human judges are so ready to give the benefit of the doubt when conversational responses are capable of being interpreted as "intelligent".
It’s best to have very specific intents, so that you’re clear what your user wants to do, but to have broad entities – so that the intent can apply in many places. For example, changing a password is a common activity (a narrow intent), where you change your password might be many different places (broad entities). The context then personalises the conversation based on what it knows about the user, what they’re trying to achieve, and where they’re trying to do that.
Once your bot is running in production, you will need a DevOps team to keep it that way. Continually monitor the system to ensure the bot operates at peak performance. Use the logs sent to Application Insights or Cosmos DB to create monitoring dashboards, either using Application Insights itself, Power BI, or a custom web app dashboard. Send alerts to the DevOps team if critical errors occur or performance falls below an acceptable threshold.
Each student learns and absorbs things at a different pace and requires a specific methodology of teaching. Consequently, one of the most powerful advantages of getting educated by a chatbot is its flexibility and ability to adapt to specific needs and requirements of a particular student. Chatbots can be used in a wide spectrum, be it teaching people how to build websites, learn a new language, or something more generic like teach children Math. Chatbots are capable of adapting to the speed at which each student is comfortable - without being too pushy and overwhelming.
But, as any human knows, no question or statement in a conversation really has a limited number of potential responses. There is an infinite number of ways to combine the finite number of words in a human language to say something. Real conversation requires creativity, spontaneity, and inference. Right now, those traits are still the realm of humans alone. There is still a gamut of work to finish in order to make bots as person-centric as Rogerian therapists, but bots and their creators are getting closer every day.
Great explanation, Matthew. We just launched bot for booking appointment with doctors from our healthcare platform kivihealth.com . 2nd extension coming in next 2 weeks where patients will get first level consultation based on answers which doctors gave based on similar complaints and than use it as a funnel strategy to get more appointments to doctor. We provide emr for doctors so have rich data there. I feel facebook needs to do more on integration of messenger with website from design basis. Different tab is pretty ugly, it should be modal with background active. So that person can discuss alongside working.
This machine learning algorithm, known as neural networks, consists of different layers for analyzing and learning data. Inspired by the human brain, each layer is consists of its own artificial neurons that are interconnected and responsive to one another. Each connection is weighted by previous learning patterns or events and with each input of data, more "learning" takes place.

There is a general worry that the bot can’t understand the intent of the customer. The bots are first trained with the actual data. Most companies that already have a chatbot must be having logs of conversations. Developers use that logs to analyze what customers are trying to ask and what does that mean. With a combination of Machine Learning models and tools built, developers match questions that customer asks and answers with the best suitable answer. For example: If a customer is asking “Where is my payment receipt?” and “I have not received a payment receipt”, mean the same thing. Developers strength is in training the models so that the chatbot is able to connect both of those questions to correct intent and as an output produces the correct answer. If there is no extensive data available, different APIs data can be used to train the chatbot.
"From Russia With Love" (PDF). Retrieved 2007-12-09. Psychologist and Scientific American: Mind contributing editor Robert Epstein reports how he was initially fooled by a chatterbot posing as an attractive girl in a personal ad he answered on a dating website. In the ad, the girl portrayed herself as being in Southern California and then soon revealed, in poor English, that she was actually in Russia. He became suspicious after a couple of months of email exchanges, sent her an email test of gibberish, and she still replied in general terms. The dating website is not named.
